Problems solved by technology

The combined structure of the bucket and the excavator enables the excavator to use the bucket to easily move and lay steel plates on the ground, but it is not suitable for foundation pit excavation construction
[0003] In the process of foundation pit excavation, most slope repairs are carried out directly with excavators using buckets. The poor forming effect also has a certain impact on the slope support construction, and the slow progress has a certain degree of impact on the sub-item construction period of the project.
Especially when the engineering soil is cohesive, the working efficiency of the excavator is low in the actual construction process, the surface layer of the repaired slope is rough, and the construction speed is slow
[0004] Therefore there are above-mentioned various inconveniences and problems in the combined structure of known bucket and excavator

Embodiment 1

[0033] The excavator bucket scraper of the present invention includes a scraper body. figure 1 It is a schematic structural view of the excavator bucket scraper according to the embodiment of the present invention, figure 2 for figure 1 Sectional view of A-A in Fig. As shown in the figure, the scraper body includes a rectangular steel plate adapted to the bucket of an excavator, and a bucket tooth seat is fixedly welded to both ends of the long side of the rectangular steel plate, and the tooth seat has a right-angled trapezoidal cross section. , The tooth seat is provided with bolt holes that pass through on both sides, and the tooth seat cooperates with the teeth of the excavator bucket, so that the bucket teeth can be inserted into the tooth seat, and the bolts are used to pass through the bolt holes for fastening. The rectangular steel plate has a thickness of 20mm, a length of 1.5m and a width of 300mm. The bolt diameter is 20mm. The bucket tooth seat is a commercial...

Embodiment 2

[0035] image 3 It is a schematic diagram of the use state of the excavator bucket scraper and the excavator bucket installed together according to the embodiment of the present invention. The installation method of the excavator bucket scraper of the present invention comprises the following steps:

[0036] a. Put the excavator bucket scraper that has been welded with the tooth seat upright, so that the hole at the upper bottom of the right-angled trapezoid is upward, and the teeth on both edges of the bucket are inserted into the tooth seat. The tooth seat and scraper are welded with E43 welding rod. The tooth seat can be made by the personnel themselves. The thickness of the steel plate is 30mm, so that the height of the right-angled trapezoid of the tooth seat is 100mm, the width of the upper bottom is 110mm, and the width of the lower bottom is 60mm. 100mm wide and 80mm high.

[0037] b. Check the insertion depth of the teeth on the two edges of the two buckets, whethe...

Abstract

A scraper for an excavator bucket comprises a scraper body and is characterized in that the scraper body comprises a rectangular steel plate matched with the excavator bucket, and two bucket tooth seats are fixedly welded to the two ends of one side of the long edge of the rectangular steel plate along the surface respectively, the section of each bucket tooth seat is in a right-angle trapezoid shape, each bucket tooth seat is provided with a bolt hole with the two sides communicating with each other, the bucket tooth seats are matched with bucket teeth of the excavator bucket, and the bucketteeth can be inserted into the bucket tooth seats and are fastened by penetrating bolts into the bolt holes. The scraper for the excavator bucket and a mounting method thereof have the advantages thatthe scraper is simple in structure and convenient to manufacture, the mounted scraper makes the repair speed of a slope of a foundation pit remarkably improved, the one-time molding effect of the slope is good, the scraper can be repeatedly used, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to an auxiliary attachment device for an excavator bucket, in particular to an excavator bucket scraper and an installation method thereof. Background technique [0002] Chinese patent CN110409526A disclosed a bucket and an excavator on November 5, 2019, wherein the bucket is welded by a bucket bottom structure, a side sealing plate, a shaft seat, and a main knife plate, and the bucket bottom structure includes a bucket bottom plate, a bucket bottom The reinforcing plate and the bucket bottom reinforcing plate are bonded and welded on the bottom of the bucket bottom plate. Multiple holes are arranged on the overlapping area between the bucket bottom reinforcing plate and the straight part of the bucket bottom plate, and a magnet is fixedly installed in each hole. The combined structure of the bucket and the excavator enables the excavator to use the bucket to easily move and lay steel plates on the ground, but it is not suitable f...
